The high-pressure differential scanning calorimeter (HPDSC) is well suited to the measurement of heat of vaporization (HOV) of these fuels at atmospheric pressure and the production of enthalpy curves, at various pressures. These data are used for the construction of master enthalpy diagrams.
Enthalpy diagrams are used for determining the state of the fuel in the design of fuel systems for jet engines and their operability calculations. Different types of fuel injectors in engine main combustors and auxiliary power sources generate many different spray droplet sizes and in several different environments, and these master enthalpy diagrams curves help to determine vapor generation for ignition analysis. These curves provide a source of information when trying to understand what has happened in an aircraft accident and aftermath or a fuel spill and fire investigation. HOV is also used in the study of events where fuel vapor production is an important part of an analysis preceding fire initiation, such as in an observed tailpipe fire.
